The nickname 'Spaghetti Junctions' is used for complicated and intertwining road traffic interchanges — which resembles spaghetti on a plate. Similarly, there are 'clover-leaf junctions' and 'floral junctions' as well, but the first one is the most common. The term is said to have been first used in 1965 to describe the Gravelly Hill Interchange on the M6 motorway in Birmingham, UK. Now, many interchanges across the world have acquired the nickname. With elevated interchanges going as high up as four levels (Shanghai, China, etc.) and five levels (Texas, USA, etc.), there's nothing straight about these roads in this list.
